Painting conservation using laser ablation has been the subject of many recent studies – exploring both the possibilities and limitations of the technique.
In this study, two laser cleaning approaches using UV laser pulses of femtosecond (fs) and nanosecond (ns) durations allow controlled micrometric layer removal of varnish on coloured temperas. These results widen the choice of laser conditions for painting restoration.
